New Method Shows Promise to Grow Photonic Crystals with Relative Ease

Highly purified crystals that split light with uncanny precision are key parts of high-powered lenses, specialized optics and, potentially, computers that manipulate light instead of electricity.

Scientists Uncover Secret to Twisting Light

Scientists at The Australian National University (ANU) have uncovered the secret to twisting light at will. It is the latest step in the development of photonics, the faster, more compact and less carbon-hungry successor to electronics.

SPP-Based Polarization Filter Composed of Multiple Holes Array with Nonlinear Medium Can Realize Polarization Separation

As we all know, some optical devices can only work with a certain incident polarization direction. In this case, a polarizer is necessary to shift the polarization direction of linearly polarized light.

Array of Pillar-Bowtie Nanoantennas Can Record Light Smaller Than its Wavelength

Researchers at the University of Illinois at Urbana-Champaign have demonstrated that an array of novel gold, pillar-bowtie nanoantennas (pBNAs) can be used like traditional photographic film to record light for distances that are much smaller than the wavelength of light (for example, distances less than ~600 nm for red light).

New Kind of Photoresist Needed to Extend Moore's Law

Over the years, computer chips have gotten smaller thanks to advances in materials science and manufacturing technologies. This march of progress, the doubling of transistors on a microprocessor roughly every two years, is called Moore's Law.

Coordinated Vibrations Between Hydrogen-Bonded Molecules Visualized Using Ultrafast Femtosecond Infrared Light

Using a newly developed, ultrafast femtosecond infrared light source, chemists at the University of Chicago have been able to directly visualize the coordinated vibrations between hydrogen-bonded molecules -- the first time this sort of chemical interaction, which is found in nature everywhere at the molecular level, has been directly visualized. They describe their experimental techniques and observations in The Journal of Chemical Physics, from AIP Publishing.

Raman Spectroscopy Combined with Intricate Optical Amplifier to Create Powerful Molecular Sensor

Nanophotonics experts at Rice University have created a unique sensor that amplifies the optical signature of molecules by about 100 billion times. Newly published tests found the device could accurately identify the composition and structure of individual molecules containing fewer than 20 atoms.
